How can we reduce carbon emissions from heating?

Decarbonisation of Heating Systems: Paving the Way Towards a Sustainable Future

Article by Ergin Kaya, Senior Energy Consultant at Optimised, who shares his knowledge on the decarbonisation of heating systems and why it’s so critical for reaching net zero 2050.

The UK has set an ambitious goal to achieve net-zero emissions by 2050, and a crucial aspect of attaining this target lies in the decarbonisation of heating systems in buildings.

 

In essence, decarbonisation involves either avoiding the release of CO2 emissions into the atmosphere or actively removing them. The levels of CO2 in the atmosphere have surged significantly alongside the global population growth since the industrial revolution.

 

Several factors contribute to the rise in CO2 levels, including population growth and declining forest areas. However, the most significant contributor is direct CO2 emissions resulting from the combustion of fossil fuels in transportation and heating systems.

What is heat decarbonisation?

Why decarbonising heating systems is essential for net zero

Decarbonising heating systems is essential because they represent a major source of carbon emissions in both the UK and the world, significantly contributing to global warming. In the past, coal was commonly used for heating purposes, leading to severe air pollution and health hazards. Fortunately, the transition to natural gas improved air quality, but the need for further decarbonisation persists.

 

Heating systems play a vital role in achieving the urgent need to combat climate change and transform our energy systems. The transition to decarbonised heating is essential for reaching global carbon reduction goals. The UK government has set ambitious targets for installing heat pumps in domestic properties, aiming for 600,000 installations annually by 2028 to support net zero 2050.

What are the key technologies for decarbonisation?

4 main technologies for decarbonising heating systems

Heat Pumps, offer a sustainable heating solution to replace traditional gas fired boilers for the provision of heating and hot water, through utilising renewable energy sources, and can be ground, air, or water-source technologies. Heat pumps can be complex to retrofit to existing assets, due to space limitations and efficiency concerns depending on the building fabric.

 

Hydrogen Boilers, powered by green hydrogen, emit only water vapor when burned, making them a carbon-neutral alternative to natural gas. The supply of readily available hydrogen is still in development to meet the expected demand, and the transition to hydrogen is likely to play a key role in the pathway to net zero by 2050. 

 

Renewables, and synthetic alternatives to Liquid Natural Gas (LNG), such as biogas, hydrotreated vegetable oil (HVO) and Synthetic Natural Gas (SNG), present pathways for greener heating solutions through a lower carbon fuel.

 

Biomethane, derived from organic waste materials, holds promise in decarbonising heating systems. It can be injected into existing gas grids or used in dedicated biomethane boilers, reducing carbon emissions and contributing to a circular economy.

Where to start with decarbonising your heat consumption

How your business can MOVE towards  net zero

Before taking action to decarbonise heating systems, conducting an energy audit is a wise move. By understanding and optimising energy demand through energy efficiency measures, we can minimise consumption and pave the way for a smoother transition to decarbonised solutions.

 

Before making major changes to heating systems, analysing the demand side is crucial for an optimised solution. Collaborating with energy experts helps identify and minimize energy consumption through efficiency measures. This leads to cost savings and reduced emissions, aligning with net-zero goals. Energy experts also recommend suitable decarbonisation technologies, ensuring an optimised and sustainable transition. Conducting an energy audit provides data-driven insights to chart the best path towards a greener future.

In conclusion, decarbonising heating systems is a vital step towards mitigating climate change and securing a sustainable future. Combining various technologies like heat pumps, hydrogen boilers, biomethane, and others will create a comprehensive decarbonisation strategy.

 

Collaboration among policymakers, industries, and individuals is crucial in embracing these innovations and driving the transition towards a low-carbon future in the heating sector. By doing so, we can safeguard the planet for generations to come.
